ABSTRACT
Introduction: Children adapt various postures for sitting like sitting on benches and sitting on ground in school. In India, there are benches and desks in the classroom in urban setups, however in some rural areas the students sit on the floor with folded knees in an Indian traditional sitting posture. Lumbar spine and hamstring flexibility is measured by sit-and-reach-test (SRT) and active-knee-extension(90-90)-test (AKET) respectively. To date correlation between different sitting postures, flexibility in spine and hamstring among children is not yet performed in Indian school children.
Material and Methods: Four schools were selected by random number table method (2Schools with crossed leg sitting & 2schools with bench sitting posture). Permission was obtained from school authorities. Out of 7subgroups (6to12 years) each group has 60 children. Consent was obtained and test procedure was elaborately explained and demonstrated. Anthropometric data were obtained. Both SRT and AKET values were recorded.
Data analysis and Results: The STATA statistical software version 13.0. was used. Pearson's correlation moment product was used to determine correlation between anthropometric data with AKET and SRT in both genders. Regression analysis was performed to determine the contribution of anthropometric factors to AKET and SRT. Bench sitting children exhibit greater hamstring flexibility and children in crossed leg sitting exhibit more lumbar flexibility. Lumbar flexibility is found to be more in girls than boys in 6to12 years in both crossed leg and bench sitting.
Conclusion: The bench sitting children exhibit more hamstring flexibility, whereas lumbar flexibility is more in crossed leg sitting children.
